I appreciate the help everyone ... so I assume that the Dorko 300 is only an 8/8, except for the "traveler" at 6/8, and that they are not 1/4 grinds, but 3/4 hollow. That answers my questions ... and appreciate the additional info on the "low-flex, no-sing" ... besides the weight, that info is of interest to me also.

Thanks,
Noob, but slowly evolving to indoctrinated.
